Katrin, Hmm... maybe I'll be writing a fact page to go on our web-site until we get this straightened out.
1) The models at sourceforge are primarily used only for research. No commercial usage. 2) Most of the corpus are heavily copyrighted and exclude all commercial usage. Mostly because they are fully copyrighted texts and are treated as most books are... 3) Both these out of the way, our team is also attempting to put together a way for us to generate and get a free corpus based on other free sources. Where the copyright is more of a free information exchange. I think WikiNews has been looked at as well as other sources. We have a sample server applet that will eventually run on a server to allow us to mark/tag/take apart the information and generate the correct format for the training data required for the namefinder, tokenizer and POS tagger. Help on this is extremely welcome and I think you and anyone else interested can contact Jorn to get started or how to help.
